ROBERT A. CUMMINGS, OF BEAVER, PENNSYLVANIA.

PROTECTOR FOR PILES.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed. June 1, 1908. Serial No. 435,948.

To all whom it may concem.

Be it known that 1, ROBERT A. CUMMINGS, a resident of Beaver, in thecounty of Beaver and State of Pennsylvania, have invented a new anduseful Improvement in Protectors for Piles, of which the following is aspecification.

This invention relates to protectors for the ends of piles, posts andthe like while driving the same.

The invention is particularly adapted for protecting the ends ofconcrete or similar piles while driving.

The object of the invention is to provide a device of this characterwhich effectually prevents injury to or battering the end of the pileand also one which is adjustable to iit piles of different sizes.

The invention comprises a tubular member arranged to be clamped tightlyto the pile so as to not move thereon and projecting beyond the end ofthe pile to receive a cushion or cushioning material.

The invention also comprises details of construction hereinafterdescribed and claimed.

In the accompanying drawing Figure 1 is an elevation partly in verticalsection showing my invention applied to the driving of concrete piles:and Figs. 2 and 3 are horizon tal sections taken respectively on thelines 2-2 and 33, Fig. 1.

1 indicates the pile being driven, this being shown as a concrete pilehexagonal in cross section, but obviouslythc deviceis applicable topiles of any character and of any cross section. The protector comprisesa suitable tubular member secured to the pile in any suitable way so asto not move thereon and pro jecting beyond the end of the pile. Asshown, this tubular member or sleeve 2 is made up of two semi-tubularsections 3 and 4 provided on their edges with radial flanges 5 forreceiving compression bolts 6 for securing the sleeve sections together.As shown, there is a space 7 between the radial flanges which permitsadjustment of the two sleeve members to fit piles of different sizes.The flanges on one of the members are provided with right angle portions8 projecting across the ends of the flanges on the other member.

Preferably this sleeve is provided with lugs 9 for engaging the hammerguides 10, the hammer itself being indicated at 11. These lugs 9 areshown as formed integral with the t sleeve members, but obviously theymay be separate therefrom and bolted or otherwise secured thereto.

The sleeve members are tightly clamped to the pile by drawing up thecompression bolts 6 so that said sleeve is immovably secured to thepile. It projects beyond the end of the pile, as shown in Fig. 1, so asto provide a socket or space for receiving the cushion or cushioningmaterial. The latter is shown as comprising some suitable finely dividedmaterial, such as sawdust 12, filled into the sleeve on top of the pile,and covered by the metal plate 13 upon which rests a block 14,preferably of oak wood and which receives the hammer blows. The block 14is preferably reinforced by a ring or ferrule 15, and the plate 13 isprovided with one or more holes 16 for the insertion of a bar forremoving the plate. The block 14 has a loose fit in the sleeve as shown.

In use the sleeve 2 moves with the pile and has no movementindependently thereof so that it does not fly up and down under theshock of the blows, and therefore practically all injury to the end ofthe pile avoided. The block 14: receives the blows of the hammer and asit has a loose fit in the sleeve the force of the blow is transmitteddirectly to the top of the pile and none of the stress of the blow fallsupon the sleeve.

By means of the device described a pile can be repeatedly driven withoutserious injury to its end. The device can be readily attached to thepile and is so constructed that it can be attached to piles of differentsizes within limits.

Various changes can be made in the device without departing from thespirit of the invention. For instance, various other ar rangements thanthose shown for effecting the adjustment of the device will readilysuggest themselves.

What I claim is:

1 Aprotector for piles, comprising a tubular member constructed to besecured immovably to the pile and project beyond the end thereto, and acushion in said tubular member and confined by the projecting endthereof.

2. Aprotector for piles, comprising a tubular member constructed to beimmovably secured to the pile and project beyond the end thereto, saidmember being adjustable to said loose cushioning material and looselyfitting tubular member.

piles of different sizes, and a cushion in said tubular member andconfined by the pro'j ecting end thereof.

. 3. A protector for piles, comprising a tubular member arranged to beimmo'vably secured to the pile and project beyond its end thereto,adjustable means for securing said member to the pile, and a cushion insaid tubular member and confined by the projecting end thereof.

4. A protector for piles, comprising a tubul lar member constructed tobe lmmoyably sei cured to the pile and project beyond the end thereto,lugs on said member for engaging the hammer guides, and a cushionfitting loosely in said tubular member and confined lar member arrangedto be secured to the pile and project beyond the end thereto, a cushionof finely divided material in the projecting end of said tubular member,a plate resting on said finely divided material, and a Wooden blockloosely fitting said tubular member and resting on said plate.

In testimonywhereof, l. have hereunto set by the projecting end thereof.my hand.
